|
|
* The #clutter_texture_set_from_rgb_data and #clutter_texture_set_pixbuf are
|
2006-09-19 19:27:16 +00:00
|
|
|
* used to copy image data into texture memory and subsequently realize the
|
2007-05-25 10:56:09 +00:00
|
|
|
* the texture.
|
|
|
|
*
|
|
|
|
* If texture reads are supported by underlying GL implementaion
|
|
|
|
* Unrealizing/hiding frees image data from texture memory moving to main
|
|
|
|
* system memory. Re-realizing then performs the opposite operation.
|
|
|
|
* This process allows basic management of commonly limited available texture

* configure.ac: Enable debug messages also when
--enable-debug is set to "minimum".
* clutter/Makefile.am:
* clutter/clutter-debug.h: Move all debugging macros inside
this private header; make all debug macros depend on the
CLUTTER_ENABLE_DEBUG compile time define, controlled by
the --enable-debug configure switch; add G_LOG_DOMAIN define.
* clutter/clutter-main.c: Clean up the debug stuff; add
command line argument parsing using GOption; the debug
messages now are triggered like this:
CLUTTER_DEBUG=section:section:... clutter-app
or like this:
clutter-app --clutter-debug=section:section:...
where "section" is one of the sections listed in clutter-main.c,
or "all", for all sections; each section is bound to a flag,
which can be used to define a domain when adding a debug note
using the CLUTTER_NOTE() macro; the old CLUTTER_DBG() macro is
just a wrapper around that, under the CLUTTER_DEBUG_MISC domain;
CLUTTER_NOTE() is used like this:
CLUTTER_NOTE (DOMAIN, log-function);
where log function is g_printerr(), g_message(), g_warning(),
g_critical() or directly g_log() - for instance:
CLUTTER_NOTE (PANGO, g_warning ("Cache miss: %d", glyph));
will print the warning only if the "pango" flag has been
set to the CLUTTER_DEBUG envvar or passed to the --clutter-debug
command line argument.
similar to CLUTTER_SHOW_FPS, there's also the --clutter-show-fps
command line switch; also, the --display and --screen command
line switches have been added: the first overrides the DISPLAY
envvar and the second controls the X screen used by Clutter to
get the root window on the display.
* clutter/clutter-main.h:
* clutter/clutter-main.c: Add extended support for GOption
in Clutter; use clutter_init_with_args() to let Clutter
parse your own command line arguments; use instead
clutter_get_option_group() to get the GOptionGroup used by
Clutter if you want to do the parsing yourself with
g_option_context_parse(). The init sequence has been verified,
updated and moved into common functions where possible.
* clutter/pango/pangoclutter-render.c:
* clutter/*.c: Include "clutter-debug.h" where needed; use
CLUTTER_NOTE() instead of CLUTTER_DBG().
* examples/super-oh.c: Use the new clutter_init_with_args()
function, and add a --num-hands command line switch to
the SuperOH example code controlling the number of hands at
runtime.

* configure.ac: Enable debug messages also when
--enable-debug is set to "minimum".
* clutter/Makefile.am:
* clutter/clutter-debug.h: Move all debugging macros inside
this private header; make all debug macros depend on the
CLUTTER_ENABLE_DEBUG compile time define, controlled by
the --enable-debug configure switch; add G_LOG_DOMAIN define.
* clutter/clutter-main.c: Clean up the debug stuff; add
command line argument parsing using GOption; the debug
messages now are triggered like this:
CLUTTER_DEBUG=section:section:... clutter-app
or like this:
clutter-app --clutter-debug=section:section:...
where "section" is one of the sections listed in clutter-main.c,
or "all", for all sections; each section is bound to a flag,
which can be used to define a domain when adding a debug note
using the CLUTTER_NOTE() macro; the old CLUTTER_DBG() macro is
just a wrapper around that, under the CLUTTER_DEBUG_MISC domain;
CLUTTER_NOTE() is used like this:
CLUTTER_NOTE (DOMAIN, log-function);
where log function is g_printerr(), g_message(), g_warning(),
g_critical() or directly g_log() - for instance:
CLUTTER_NOTE (PANGO, g_warning ("Cache miss: %d", glyph));
will print the warning only if the "pango" flag has been
set to the CLUTTER_DEBUG envvar or passed to the --clutter-debug
command line argument.
similar to CLUTTER_SHOW_FPS, there's also the --clutter-show-fps
command line switch; also, the --display and --screen command
line switches have been added: the first overrides the DISPLAY
envvar and the second controls the X screen used by Clutter to
get the root window on the display.
* clutter/clutter-main.h:
* clutter/clutter-main.c: Add extended support for GOption
in Clutter; use clutter_init_with_args() to let Clutter
parse your own command line arguments; use instead
clutter_get_option_group() to get the GOptionGroup used by
Clutter if you want to do the parsing yourself with
g_option_context_parse(). The init sequence has been verified,
updated and moved into common functions where possible.
* clutter/pango/pangoclutter-render.c:
* clutter/*.c: Include "clutter-debug.h" where needed; use
CLUTTER_NOTE() instead of CLUTTER_DBG().
* examples/super-oh.c: Use the new clutter_init_with_args()
function, and add a --num-hands command line switch to
the SuperOH example code controlling the number of hands at
runtime.
